Yazmin, it's times like the one you found yourselves in that a true body-on-ladder frame 4WD with locking rear ends and a little more aggressive tread tires
comes in really handy for towing, even with a lightweight trailer like your Boler
. Having been stuck just on wet grass in 2WD trying to leave a campground, it's comfortable to have the 4WD with locking rear ends available. And as Paul said with a front wheel drive car on a hill in a soft surface you lose even more traction towing.
If you drive on back roads, good gas mileage doesn't count for much when you're stuck by yourself in the middle of nowhere in a rut, really soft gravel, or mud at midnight and you find your drive tires
are spinning because your trailer tires
are buried too.
Just a thought to put away for next time you think about a new tow vehicle.
